Oppex sits transparently over your browser window while you solve algorithmic challenges. Analyze edge cases, calculate time complexity, and receive optimal code logic without ever switching tabs or losing your workflow context.
Floats cleanly on top of LeetCode, HackerRank, or Codeforces without hooking browser DOM or triggering anti-tamper extensions.
Instantly suggests O(N) or O(log N) optimal approaches with full Big-O analysis and memory constraints before you submit.
Oppex operates through your local desktop client. Code solutions and screenshots are never stored or used to train external models.
